Type locality: “Coromandel”  
TypesHolotype: BMNH 1946.1.9.23 (type, female, from Sunderbunds, Bengal, Dr Russell, R. College of Surgeons coll); previously listed as lost (fide NGUYEN et al. 2009). 
DiagnosisDiagnosis: Scale rows around neck 27–35, rarely 25; scale rows around body 37–47; ventrals 27–30. Maxillary teeth behind fangs 5–8. Colouration: Very variable, especially the bands. Body pale yellow green or greyish above, whitish below. Dark bluish or black bands, which may be: a) encircling the body and broadest above, b) encircling the body and of rather uniform width, or c) broadest above and narrowing out to dis- appear laterally. On the posterior part of the body the bands are dorsally always broader than the interspaces between them. With age the banding pattern fades (see also REZAIE-ATAGHOLIPOUR et al. 2016: 152) 

Synonymy partly after STEJNEGER 107.

Habitat: marine.

Distribution: not on the Solomon Islands by McCoy 2015 although reported from there by McCoy 2000. In Qatar fide Wikipedia.
